Hello ,
I just put my opinion. I won’t talk about technique, most of you are beyond me. I will therefore speak as a user.
AGO has reached a level where I cannot imagine using another autoguiding solution.
I am for evolution, and UDP seems to me the way. The Ethernet speed, the barrier of distance, the low cost of the material, the ease of finding components widely used in all areas, are points that eliminate other solutions. CAN is beautiful for isobus , but so closed is finally not so fast , nor so beautiful as ethernet… Watch the loading time of an implement in the VT of your tractor !!
I am however a USB user, for the moment, but if UDP makes it possible to go further in your desires for the development of AGO, for example as mentioned by brian computer vision, it is necessary to go in this direction.
Ethernet is something very common.
Please keep commenting, your thoughts are driving important decisions. It appears like we don’t have anyone scared of using Ethernet/uDp. That is great news.
I hope the best for everyone. Great things coming from Brian and team. Hold in there I promise miles of discussion has been had on developers site trying to find the best options for you all.
God bless.

I’d like a hand to hold for setting up udp. Is there a video on this? I think the gps and auto steer should be separate to the machine and imu module. But maybe have the auto steer board be capable of turning off 1 section?
Brain ( mistake but reality )
for the extra connector
Is it possible to make a connexion with individual +5v / gnd / for each in/output that can be more easy to connect extra sensor or device on future
I’m not sure I understand your request. Are you talking about how to set up a specific board or a Ethernet network?
Why a router is needed cant it be just LAN network with ethernet hub?
Yes it can
UDP works very well for me, USB ports are somewhat amateurish and unsafe for this system, tractor vibrations due to terrain and the expansion of USB port over time make the system unsafe, what if we can connect an IP camera to the switch and use it to see the equipment behind on the AOG screen while using UDP. it would be fine.
It can be either a router or a switch. Router being the one, maybe poorly named, that includes wifi. It would allow a wifi connected esp32 for example way back on the tool wirelessly.
In AgraBot, i used wifi and wired so i could keep an eye on AOG in the robot tractor rolling seeded peas using TeamViewer to see what was going on on my phone while i was in the other tractor seeding. This would not be possible with serial 
Wifi is just replacing the ethernet cable with radio waves so you can use some, none or all with it. The only challenge i found with wifi and a normal wifi router was data is sent in bursts. So you could do 50 hz gps except it would bunch them together and still only achieve 3 or 4 updates per second.
Have you noticed this? Or using different router? Different type of Access point?
So cool what you have done with Open Grade!
So section control for usb has to be close to tablet but for UDP ethernet can be taken to sprayer or wireless but for that ruter is needed ? I use mobile hotspot for internet to tablet will that work as ruter for esp32 ?
For ethernet hub, theres “switches” and “spliters” with spliters allowing only one connection at a time are they good for AOG or simultaneous connection is needed ?
That’s right and I would say that flexibility to have a combo of wired/wireless modules is one of the biggest advantage of a protocol like UDP.
I haven’t found the data issues, although I haven’t taken it to 50 but it seemed to handle 30hz just fine. I have a esp 32 running in the antenna module it simply reads the serial data coming out of the RTK2B and as soon as it reads The whole NMEA line it just fires it over the UDP network. That ESP also acts as the Acess Point for the network. (The OpenGradeX I connect to in the video is that Acess point)
The only little bit of weirdness I have found is I have recently undertaken adding NTRIP client to the project. When the client connects for the first time I can see a small delay in the GPS Fix, but it usually sorts itself out within a half a second or so. Don’t know if TCP takes priority over UDP on the network or something like that. I’m just a farmer after all.
As far as I am concerned I have just put the icing on the cake when it come to Opengrade. The whole cake was sitting there waiting for me with work done by yourself and others in this forum.
We are working on a simple set of instructions with screenshots to set the tablet up for UDP. We will post it as soon as its ready
As long as you end up with a functional network where everything can see everything - you can really do pretty much anything. You can even make esp32 an access point and use it as the wifi router. You would essentially connect to the machine module lol.
You can see the possibilities spread out ! No shortage or limitations at all - just precious time.
Now imagine this. Attach a high speed udp camera to the spot above the right front wheel looking ahead. Use OpenCV computer vision and do tramline guidance following the tram dark line.
Plant rows - make a line via camera of the desired plants - steer the tool to steer between the rows. No gps even required.
Tony is trying this board out. It is a PANDA (single antenna and roll timed together) so it is a pretty ideal gps. Can be usb or udp. Ideal solution for pre built systems. Or as i like to think of it future as well using this board and the old style steer board.
Ridiculously cost effective and reliable GPS system. We also hope to be able to program the F9P thru the udp as well.
Well wifi ntrip master can be connected to AOG? It has option to forward wifi network that its conneted so section control esp32 connected to wifi ntrip master, phone as main wifi for esp32 and tablet or some combination of that. Theres always bluetooth.
But probably not so simple 
Is there good wireless setup explained or possible?
Really nice, i want to Do the same… Can the UDP Code and PCB be shared. Would be a nice unit!
